Title: Ultra sonic cleaning unit using cavitation fluid - transmits vibration from transductor via chamber containing material less liable to cavitation
Inventor: KLOEGMAN SIMON RONALD
IPC: B08B3/12
Filed: 1974-05-10
Abstract: The unit has a cleaning tank for the application of fluid in which cavitation occurs when subjected to vibration. This is produced by one or more transductors fitted to a first radiation surface, while a second one forms part of the tank wall. The two surfaces enclose a chamber filled with a material transmitting the vibration between them, so that the second one in turn transmits it to the fluid. The material between them is so selected that it suffers virtually no cavitation as a result of the vibration, and ethylene glycol can be used for this purpose. The section of tank wall where the transductor is mounted can be made removable.

Patent DE-2449151-A1 (DE)
Title: Mixer for liqs. and or powders - for application of sprayed coatings, adhesives etc.
Inventor: IFFLAND HELMUT ING GRAD
IPC: B05B7/04
Filed: 1974-10-16
Abstract: A mixing device for liqs. and/or powdered material consists of a forward mixing chamber, and a rear mixing chamber into which the materials to be mixed are introduced and in which a driven mixing propeller rotates. The propeller bearing is located in the wall of the mixing chamber. The novelty lies in the provision of a duplex transverse bearing and the rigid attachment of a further mixing propeller in the forward chamber to that in the rear chamber. Used in hand held spray guns for paint, adhesive, resins etc. The correct play in the bearing is automatically set by assembly of the outer housing components which have flat mating faces to maintain correct spacing. In the event of malfunction, the mixer can be quickly dismantled before the mixed media harden inside the device. The mixing propeller in the forward mixing chamber prevents a build-up of hardened deposits on the chamber wall. Passage of the mixed materials through a double bearing improves mixing.
